METHOD AND APPARATUS FOR RADIO FREQUENCY DRYING OF TEXTILE MATERIAL

摘要

Textile material to be dried is mounted in an apparatus on a plurality of supports (1). The supports are moved along a predetermined path, and suction and radio frequency energy are applied to the material, to dry it. A pump (10a) which can pump both liquid and vapor draws air through the material to remove water. A valve (12) is associated with the suction duct (2) leading to each support, and these valves are adjusted as the supports move along the path, so that a maximum amount of suction is applied to the wet material and a lesser amount of suction to the drier material.
